What is this? Detritus worm?

Can someone help?

Looks like snail eggs to me.

Yup, what he said.

Crossing my fingers the trochus snails have left eggs then.

Trochus had been known to reproduce in the aquarium but, they have a free swimming (pelagic) larval stage which makes it likely that few, if any, will make it to a juvenile stage. Filtration, filter feeders, fish, etc are likely to remove the larval stage.

So do some additional digging pretty sure these are cerith snail eggs. Which I am not complaining about at all either.

Dang thats cool, keep us updated as you grow your snail army!

Yes, Ceriths are known to readily lay eggs in aquariums. Now that you mention you have Ceriths, that is very likely what they are.

So I do now have some small cerith snails showing up on the glass, which is pretty cool to be honest. They do suck up a lot of calcium and alkalinity though. Expected as they are forming a shell but was not yet ready for it.

Snails shouldn’t impact you Alk and Ca that much. IMO, I’d be looking for another reason.
